The process took 3 weeks. I interviewed at AT&T (New York, NY) in Jan 2010
Interview
In my first phone interview, I was given extensive information about the company and the different divisions including the division I was applying for. I had to wait one week before scheduling my in person interview. During that interview, I met with 2 different people for 30-45 minutes each answering basic questions about my past experience, where I see myself in 5 years, what are my strengths and weaknesses, etc. After another week I was called back for a second interview where I met a couple more people and repeated the same process. The questions were not difficult. One week after that I received a call from HR extending an offer.

Peer and supervisor interviews. 1 on 1 and panel interviews. Pretty relaxed and informal. I was progressing from one AT&T position to another, so knew all the stakeholders.
